1 Claim.

This invention relates to devices for dispensing plastic substances,such as pastas, creams, unguents, etc., from a container havingcollapsible walls, which upon being compressed cause the contents toexude.

An object of the invention is to provide a holder for such containers,secured in any convenient location, and having means to retain the typeci collapsible tube usually employed therein.

A further feature is in the provision of means, operatively combinedwith the holder, to cornpress the walls of the tube to any desiredextent whereby a suitable portion of its contents is delivered from itsmouth.

Another purpose is to provide a stopper for the mouth of the tube,preventing leakage and waste, and also the possible entrance of dirt andforeign substances.

These and other advantageous objects will become'apparent in thefollowing description, taken in connection with the accompanyingdrawing, forming a material part of this disclosure, and in which:-

Figure l is a side elevational view of an embodiment of the invention.

Figure 2 is a longitudinal sectional view taken on line 2 2 oi Figure 1,and drawn to an enlarged scale.

Figure 3 is a transverse sectional view vtaken on line 3-3 of Figure 1.n

Figure 4 is a similar sectional view taken on line 4-15 of Figure 2.

Figure 5 is a perspective view of the tube and roll carrier.

Figure 6 is a fragmentary view showing a modied form of stopper.

The device consists of a sheet metal rectangular holder IIJ having abottom secured to a wall W by fasteners il and provided with a cover I2slidably engaged by flanges extending from the upper edges of thesidewalls [3-13 which are connected by lower and upper end walls l4-|4'.

A carrier l5, slldable in the holder, is composed of a plate i6 havingits ends I1-I1 reduced in width and bent sharply at right angles andhanged outwardly, as at I8-l8', and Iii-I9', the edges of the angesbeing in slidable contact with the inner surfaces of the holder sides,as best seen in Figure 3.

A central longitudinal slot is formed in the plate Iii and pairs ofregistering openings 2I-22 are on the end elements I1-I1'.

Mounted in the openings 2| is a iixed spindle 23 on which is a revolubleroll 24 having a rubber jacket 25.

A stud 26 is riveted in the opening 22 vci! the plate i1' to act as asupport for a tube 21 on which is nxed a roll 28 covered with anabrasive 29, as emery cloth.

The opposite end of the tube is slotted transversely and extends throughthe Opening 22 in the plate l1.

Engaged with the tube slots is a dog 36 on the inner end of a driver 3lhaving a slot 32 in which is entered one end of a coiled torsion spring33 contained in a cap 34 slidably attached to the holder side i3, thisside having a longitudinal slot 35 in which the driver 3l is free totravel, the driver being yprovided with a manually operable knob 3S,which, due to the action of the spring transmits motion in one directiononly and prevents reverse movement by reason of its expanding toforcibly contact the interior of the cap. Y

A collapsible tube T has its dat end engaged in the slot 20 of thecarrier plate I'S, between the rolls i4-28, see Figures 2 and 3, itsneck extending thru an opening 31 in the bottom wall I4 of the holder,so that as the knob is turned the tube is squeezed between the rolls ina. manner considered clearly apparent.

The neck of the collapsible tube is firmly held between a serrated clip38, fixed on the bottom plate, and similar seri-ations on a. lever 39,pivoted at 40 to the plate I4 and normally drawn into engagement by atension spring 4|.

In order to cover the orice in the end of the tube neck a plate lever 42is hinged at 43- to the plate i4, the opposite end of the lever beingshaped to present a snap catch 44 having detent 45 engageable with aclip 46 on the plate I4 in such manner as to retain or release a stopper41, carried by the lever in or from engagement at the tube mouth. m

In Figure 6 the clamp elements 38 to 4l. are omitted and in their placeis a knurled nut 48 to be threaded on the tube neck, clamping it againstthe plate i4, as will be seen.

Although the foregoing is descriptive of the preferred embodiment of theinvention it will be apparent that minor changes may be made in itsconstruction, without the exercise of invention or conflicting with thescope of theclaims hereto appended.

Having thus described the invention, what is claimed as new and desiredto secure by Letters Patent, is: f

In a paste dispenser, a holder having a longitudinally slotted side, acarrier havingvopposed guides slidable in said holder, said carrierhaving a. pair of compression rolls non-separably mounted therein, oneof said rolls having an abradant surface and the other s yieldingsurface, manual means for rotating the abradant 5 surfaced roll, atorsion spring arranged to prevent reverse movement of said rolls, a xeddetent having serrations to engage the neck o( the coilapsible tube, a.pivoted lever, n, spring actuated serrated detent carried by said leverto engage the opposite side of the tube neck, and a hinged shutter toclose the mouth of the tube.
